5 monwealth of Massachusetts, have invented certain Improvements inMachines 'for In: serting Fastenings, of which the followingdescription, in connection with the accompanying drawings, is aspecification, like reference characters on the drawings indi a a neating hke parts in the several figures.

This invention relates to machines for insert ng fastemngsandthe'partlcular embodifnent thereof herein selected for illust-rationcomprises tack supplying and driving mechanism for a lasting andnailingmachine. This mechanism includes a hopper,

a racewa a tack separating mechanism, and a ho der to rece ve thesearated ta'ckand present it in position to be driven.

The, invention has forits general objects to provide for a more certain'and accurate supplviand delivery of the fastenings than has heretoforebeen secured, to provide means by which the fastenings can be insertedin certain articular positions in the manufacture of s oes, to renderthe supplying mocha fa ng e durable and to make provisio y gainingaccess to ceri t lons' oi the mechanism that require frequent cleaning-1 a As hereinshown the ra wayis inclined ,downwardly fiomthe', op er tothe tackseparating mechanism cause the tacks to 85 travel alonE-it bygravity: The tacks are supported;

their heads in .the' inclined raceway an therefore, usually stand withtheir stems hanging obliquely downwardly and backwardly.

A feature Qt this. IILVGIIHOH consists in providing meaps for presentingthe tacks to the tack-separating mechanism with the stem;

of the tack to'beseparated and the stem of the tacknext'zabovedt'diverging one from or blade may more -readily as betweenthe two tacks.

To this end the invention contemplates the revision of raceway-having atits dolive end a raceway section or separating 5 table comprisingtack-supporting surfaces at an angle to the tack-sup ortingsu'rfaces ofthe adjacent section, so t at the stems of the tacks onthe respective"sections'will 'diverge.

As herein shown, a separating table is provided having horizontalhead-supporting surfaces upon which the tacks pass from the inclinedraceway and which cause the stemh of the tacks to assume a verticalposition by gg" gravitation. Preferably the separating table is arrangedwith relation to the tack Separating mechanism so that the separatorblade passes between the lowermost tack on'the inclined portion of theraceway and the ad jaccnt tack on the'horizontal guide. The racewaypreferably contains one or more grooves from which the tacks aredelivered to the lower section or the tack-separating table, when one ofthe grooves is in suitable relation to the receiving groove in thetable. This receiving groove in the tablemay be in alinernen't with theraceway groove or it may be inclined relatively thereto. In .the

former case I obtainthe best results by lmakiu'g the separator bladewith a separating face inclined at an angle of about 30 -toward itsdirection of longitudinal movement. This arrangement'gives, however, along slender separating blade which is less durable than a shorter andblunter blade}.

would be. I may, therefore, inclinetthe re-f ceivinggroove of thetablewith relation to the delivering groove of the racewa as, for example, atabout30 and this a lows the face of the blade to be inclined at an angleof aboutGO .to the direction of its longitudinal movement and still havewith reference to the receiving groove .the same. angular relation sothat-thetack-is urged along that groove at the same rate as by thesharper blade. to make andwill wear longer than the more slender one.

In the of the machine misshapen tacks and forei subst ariccssometimesget into This blunter blade is easier;

the tack-separating mechanismand for this and other reasons it is quitefrequently neces sary. for the operator to gain access to the; coveredarts of the mechanism. I"have,

in acc'ort ance withone feature of the invention, provided for hqldingthis mechanism in assembled relation u on the raceway by l novel meanswhich wi l rmit the separatj-' ing mechanism 'to be qulckly attachedand] disconnected without th'e useotan tools or the removal of fasteningdevices.

shown,

thisholdingmeans comprises a supporting mama between whicll and theraceway cat lea rier the separating mechanism has a sliding fit combinedwith devic es for automatically positioning said mechanism when it ismoved approximately tocorrect position and de- 6 vices for clamping saidmechanism in place.

The tacks which are forced along the receiving groove by the separatorblade ultimately fail; into a tack holder which is movable fromreceiving position outwardly into 10 tack-driving position over'thework. a In making turn shoes havin tacked heel seats the upper isfastened totlie eel seat piece after the shoe is turned. In order to dothis the heel end of the sole is bent upwardly, the 1!? up i wipedinwardly under it, and the ta are driven in a line from the end-of theseam connecting the sole and upper at the shankon one side of, the shoeto the beginning of the seam at the shank on the other 0 side of theshoe. In order to drive the tacks 'as'near as possible to the end of theseam it is, necessary that the tack block should be narrow to enable it'to present the tack close to the upturned sole. A feature of. thisinvention consists in a 'novel construction of tack block which isparticularly adapted for tacking'in such positions as that closelyadjacent to the ends of the seam and is alstijwell adapted for tackingthe other portions 'of the shoe. In the embodiment herein shown of thisfeatureof the invention the tack block comprises a narrow carrier havinga longitudinal rece'ss in.

, whioh tack fingers. are mounted one in ad- Vance of the other andarran ed for movement in, opposite directions engthwise of the carrierfor permitting the tacks to be exelled between them. A singleendwise-acting spring is employed for pressing the two 40 tack fingerstogether,--connections being provided for this purpose between one endof the spring'and one opposite end of the spring and the opposed finger.By ,this arrangement and construction of the tack fingers and theirspring a narrow block can be obtained by which a Y tack can be drivenvery close to the end of the inseam. For further adapting this tackholder to position a tack close to the end of theiiiseam the holder ismade ta ering in transverse section, the greater wi th being y at thebottom where the holder can fit under the upwardly bent heel end portionof the '1 sole. Preferably also the tack holder is pro-.

vided on its lower side with a wiper and'this 'per has downwardly andoutwardly inl 'ned; edges. The W1 er thus presents a i rubbing facewider: than the tack derandadapted to act upon the upper to o' fofrce itinto lasted ositioii in the angle between the sole and t h 'up'to' "theend of the inseam. The wiper has a tack opening and is groovedlengthwise to receive and permit movement of the tack fingers.'iTherac'eway extends into the-hopper accidental removal.

or and between the e last bottom and. close to receive the tacks andwhere it passes through the hopper means is provided for dislodgingtacks that are incorrectly placed on the raceway and for agitating theline of tacks in the hopper-contained section of the 7 raceway. Thismeans comprises a clearer which is oscillated lengthwise of the racewayand is longitudinally extensible so that it presses yieldingly upon theupper edge of the raceway and pushes back the line of tacks as it ismoved up the raceway. A block is provided which forms a close fittingcover under which only those tacksare allowed-to pass which are properlyplaced and the block has a guiding surface over which 30 the clearerslides as it approaches the level of the raceway to dislodge the tacksthat are not correctly placed. This block is preferably so mounted-thatit can be readily removed to allow the raceway to becleared. 5 Themovement of the clearer over the guide tends to tilt it and causes it towear the adjacent face of the hopper, which is of softer metal, untilthe block becomes-loose so that misplaced tacks sometimes pass under itand clog the raceway. The present invention contemplates the provisionof a yielding device for the guide block so aras to"resist the tendencyof the clearer to tilt the guide block. By the use of this device wearof the block and hopper is decreased and liability of misplaced tacksclogging the raceway is reduced. The lockmg device also serves to holdthe block from These and other features of the invention, includingcertain combinations of parts and details of construction, will beexplained more fully in the following description, and in connectionwith theaccompanying drawings, and pointed-out in the claims.

Fig. 5 shows the re movable endblock. Fig. 6 is a bottom elevation of the tack holder. Fig. 7 is a sideview; Fig. 8 is a transverse section. Figs. 9,10, 11, and 12 show.modifications.

The hopper 100, which is supported on the frame of the machine,.containsrotarytack lifting devices that are driven through the toothed wheel 191from the main shaft of the machine. The raceway 102 extends into thehopper and tacks are supplied by the lift ing devices in large numbersto this inclosed portion of the raceway.- Those which fall upon theraceway in such position that they become suspended bytheir heads uponthe supporting. faces of the racewayfslide by gravity to and along theouter portion of the raceway to the tack-separating mechanism. At thepoint where the racewaypasses through the wall of the hopper'it is 130covered by ablock 104, wliibh has in its lowerface a groove for theheads of the tacks and permits only those tacks which are properlyarranged in alingment to pass thereunder. At the inner side of thisblock the raceway 'and the lower side of the raceway holein'the hopperand is normally held from sliding out of place by the removable cover110 which fitsover the outer portion of the raceway. It frequentl hapens, however, in the use of themac ine t at it is necessary toremoyethis cover in order to give access to the raceway, and when thisis done the block .104 is liable to be'forced out of position-by theclearer. To insure against this-occurrence a device 112 is provided forHoldin the block 104 against displacement. This holding device is shownas a spring-pressed plunger mounted in a fixed portionfof the ho per andhaving an operat lng handle engaging a cam face 105 which is formed to'retain the holder in an elevated position when the holder is liftedand.turned by the operating handle. The holder is arranged to bearyieldingly upon the upper face of the block near'itsouter end andthereby serves another purpose in resisting the tendency of the cleare.s inftheir intermittent movement tofro c the block and cause it to-wearthe relat vely soft cast iron of'the hop er which wpuld allow, the blockto become ooseand unsatisfactory in use.

The main portion of the raceway is inclined as shown, to cause tackssuspended by their heads on its upper surfaceto slide.

' down by gravity. At the delivery end of the raceway is arrangedtack-separating mechanism comprising, as shown in Fig.3, a gate 120and areciprocatory blade 124; for separating the "lowermost tack in the race-"way from those above it. The ortion' below as a removal;

the'sep'arating blade is conveniently formed 121 of the end block form asupporting table upon which said lowermost tack is sustained by its headand these faces are arranged at an angle to the head-supporting"surfaces122 of the main portion of the raceway so that the'stem of the tack tobe separated will han at an angle or diverge from the stem of t ei-nextt-ack above it-and, therefore, provide wider space for the passage ofthe end block. The upper faces separating gate than would be provided bytack stems hanging parallel to each other. Preferably the faces 121 willextend horizontally, but any inclination relative to the raceway thatwould cause the stems to diverge as described would be advantageous.After the separator gate passes between the tacks the separated tack isforced by the slotted plate 124 into a position where -it may fallthrough the vertical delivery passage 119 into. the reciprocating tackholder 125 from which it is inserted into the stock by a driver 126actuated by a usual spring not shown. It will be observed that the tackgroove in the end block is in line with the raceway. groove in Fig. 3and the separator blade 124; has asharp slender finger formed by theinclined slot in its inner edge, The best. results are obtained when theinclination of this slot is about 60 to the tack groove in the endblock, or about 30 to'the direction of the reciprocating movement of theblade. The separating fingerjs subjected to constant wear and Ihaveshown in Fig. 4 a modified arrangement in which the tack groove121in the end block below the a separator blade is formed at an angle ofabout 30 to the'groove in the racewayand the transferring edge of theblade, having the notch 117 to permit the passage of the head of thetack, is formed at an angle of about 60 to the direction of itsmovement. This still gives an'a'ngle of about the same size (60 degrees)between the groove and the slotin the blade 50 that the advance of thetack along the groove is the same as before, but the separating fingeris blunter and therefore more substantial and durable. The separatingtable and the end block 123 of the raceway form, with the errd face ofthe raceway sect-ion 102, a guideway for the separator blade which isactuated endwise by suitable connections with the tack .holder 125.

The end block and its associated parts are, as shown in Fig. 5,removably held in -place by a supporting plate 127 provided with holdingmeii'ib'ers .129 having tongue and groove connections with tl1e.end.-block and a locating recess to receive-the spring: pressed,locatmg pin 131 having a beveled lower end. The supporting plate 127 isitself clamped to the raceway carrier by thumb bolts lfid'yi'hich extendthrough open ended slots in the plate and permit the plate itself to beremoved when they are lcoseiied.

It is not necessary, however, to remove the late in order to remove theend block. en theiclaufkping thumb nuts are loosened they havesu cientplay in their slots to permit the removalof the block without entirelyremoving the plate. When the block is replaced it is simply slid endwiseto the left (Fig. 5) behind the holding members 129 until the pin 131snaps into the hole inthe plate whereupon the block and its su portingplate arepressed inward and tie thumb nuts tightened to clamp the blockin position against the raceway support.

' The tack holder 125, which'is actuated by suitable mechanism forwardlyfrom receiving position directly under the separating mechanism intoposition over the work into which the tack is to be driven, is shownmore in dotail in 6, -7, and 8. The holder has laiackand driver passa e182 in which a tack may be supported y the b fingers 184, pivoted at 185in the fore part of a longitudinal groove 188. The fingers 1 arearranged one in advance of theother, as shown, to allow .the tack holderto be made'narrow. -This-is particularly desirable-in machines used-forlasting the heel seats of turn shoes, for in this work, in 29 which thetackholder is advanced over the shoe bottom into sition for the tacktherein to be driven or securing the upper in its overworkedposition,.,it is necessary-that the tack holder advance under theupturned 2 .heel end .of the sole and drive tacks as close as possibleto the angle between the sole and the end offthe inseam. The fingers 184are yieldingly held ressed together to support the tac ,but alihw thedriver to force th e tack therebetw een, by means which includes.

.a loop 186 seated in a groove in the front finger and extending"rearwardly Wltll ts side arms embracing the sides of the fingers. The-rear ends of the'side arms are inturned to form hooks that extendthroughthe walls of a spring case and terminate between two collars on aplunger 192. .The plunger is engaged by a spring 190 seated 'inthe caseand the front end of the lunger rests in a '40 recess in the back sideof t e rear finger 18.

-. With this arrangement theone spring 190 acting in one'directionthrough the loop 186 and in the reverse direction through theplunger 192 holds the two fingers yie din 1y i 4. toward each other withequal forces. he

ends of the loop stand in the space 194 betweenthe caseiand-fithe-'reduced portion 192- of the plunger and by limitingv the forwardmovement of theplunger centerthe two tack 9' fingers with relation tothe driver passage 182.; Not only is the tack holder'made narrow byarranging the tack fingers and their associated parts as. described, atthe slde faces of the holderare inclin f upwardly and inwardly towardeach other, as shown 8, to conform -them tothe-position' of the upwardlybent face of the sole and allow a tack to be driven as7close*?as Poss1--'ble to the" "end of th inseam. Preferably V and as shown, the tackholder carrieson its;

lowerside-a' wiper 196 which is the 'device thatforces the upper intoposition to be secured, or assists in doing so. The edges of this wperlare inclined like the sides of-the raceway t holder soth'at thewiper has a broad'lowr,

ranged one in advance of the other lengthwise of the tack holder and areheld in tacksupporting position by suitable coiled;

springs. In the construction shown in Fig. 10 thetack fingers arearranged tgansversely of the block and are held in posit] on by leaf- 8osprings1 204. In both Figs. 10 and 1242119.

tack gers are arranged .to slide outwardly and upwardly with relation tothe driver passage to permit the'tack to be driven. In Fig. 11 the tackfingers are shown as spring 5 pressed plungers 205 arranged to s li edownwardly and outwardly 1n guideways extending obliquely with relationto the driver passage-182. In Fig. 9 the fingers or plungers 205 slidehorizontally outwardly go as the driver forces the tack downwardly. Inthe use of the machine the tack lifting devices deposit tacks upon theportion of the tacks that enter the raceway groove properly. 5 slideunder the block 104 andthose that gather at the entrance are dislodgedby the clearer 106,, the shaft of which receives an intermittent rockingmotion from the wheel 7 101.
